MAX JAEGER, OFMOUNTVERNON, NEW YORK.

MECHANICAL LUBRICATOR.

To all whom it may concern:

Be it known that I, MAX J AEGER, a citizen of the United States, and a resident of Mount Vernon, in-the county of Westchester and State of New York, have invented a new and Improved Mechanical Lubricator, of which the following is a full, clear, and exact description.

This invention relates to lubricators, and has for an object to provide an improved structure which may be continuously operated and caused to feed any desired quantity of oil either continuously or intermittently to an article or piece of machinery being lubricated.

Another object of the invention is to provide a small, strong, lubricating device which may be adjusted at any time for varying the amount of oil used, said adjustment being designed to be adjusted while the device is running or While it is stationary.

A further object of the invention is to provide a lubricating device or pump which draws from the tank a continuous, substantially even supply of oil and forces the same out through one or more discharge openings, one of the discharge openings being a return to the tank, and the other one or more discharge openings being to the engine or various devices being lubricated, the adjustment of the various parts of the pump being such as to cause any portion of the oil drawn from the tank to be returned to the tank, the remaining part being dispensed or fed to the engine or other articles being lubricated.

A still further object of the invention is to provide a pump which may be variously adjusted so that it will continuously draw an even supply of oil from the supply tankand discharge any portion thereof back into the tank, and any desired proportion to the engine or other device being lubricated, the discharged portion of the liquid being adapted to be fed either in a continuous stream by a proper adjustment of the pump or intermittently by a proper adjustment of the pump.

In carrying out the objects of the invention the pump may be made of any desired size, and may be connected. up in any de sired manner to a power mechanism, as for instance to an engine being lubricated. It will also be evident that the various castings may be made in a number of different Specification of Letters Patent.

mechanism, preferably mounted on the chamber and arranged to control the discharge in several ways. For instance, the discharge could be caused to divide and half go back to the tank from which it is drawn and the other half discharged in a continuous stream to the engine. If this arrangement was not desired, but an intermittent arrangement was desired, certain of the parts could be adjusted'so as to intermittently discharge any proportion of the fluid forced from the chamber. The adjustment of the continuous flow of lubricant to the engine is controlled or regulated by a sliding bar or plunger. whichacts in the capacity of a valve, and which may be adjusted so as 7' gine should beintermittent a cam connected with the shaft on which the piston is mounted is caused to engage a suitable mechanism for operating a spring pressed slide. This slide is designed to engage an adjustable screw movable with the plunger or valve for controlling the discharge opening to the engine, whereby when the cam is operated and the set screw is moved the valve or plunger will'be operated for opening temporarily the discharge to the engine. The time that the intermittent discharge is flowing is determined by the length of the face of the cam which of length. 1

In the accompanying drawings :Figure 1 is a side View of a pump and valve mechanism disclosing an embodiment of the invention; Fig. 2 is a top plan view of the structure shown in 1; Fig. 3 is a longicourse may be any desired,

tudinal vertical section through the structure shown in Fig.1; Fig. 4 is a section through Fig. 3 approximately on line 4-4; .hig. is a detailed perspective view of the valve plunger controlling the return flow of oil, the same being associated with one of the end castings.

lteferring to the accompanying drawings by numeral 1 indicates a base on which is mounted a casing 2 formed with a chamber 3, the casing 2 being preIerably cast inte gral with base 1 though not necessarily so. A suitable faceplate 4 is provided for casing 2 which is bolted or secured in place in any desired manner, whereby piston 5 is properly inclosed, and whereby the chamber 3 is formed substantially airtight. The casing 2 is provided with an inlet opening 6 and an outlet opening '7, inlet opening (3 having gouged-out portions 6 and S to allow the fluid to freely flow into the casin and outlet 7 having a gouged-out portion 9 for allowing the free flow of the fluid to outlet 7. 1t willbe observed that the piston 5 is arranged eccentric to the chamber 3 so as to provide a proper action for the blades 10 and 11. It will be noted that the blades 10 and 11 extend past the center of the piston and almost entirely across the piston, whereby an ample bearing surface for each blade is provided, and also ample room for the springs 12 and 13. In operation the piston 5 is designed to rotate in the direction of the arrow shown in Fig. 3, and to draw in lubricant from any suitable tank through port 6 and force said lubricant out through port 7. The piston 5 is designed to operate continuously, and to cause the lubricant to flow as before stated, the piston 5 being operated by a shaft 14 which in turn is connected to the engine or other source of power by any desired means. v

In connection with shaft 14 it will be 01 served that the same is journaled in the boss 15 of casing 2, and also journaled in the boss 16 of standard 17, which standard .is bolted or otherwise rigidly secured to base,

1, though if desired this standard could be cast integral with base 1. Standard 17 extends above shaft 14, and is provided with a bearing portion 18, in which a journal. pin 19 is arranged. Journal pin 19 has mounted thereon a lever 20 provided witharms 21 and 22, arm 22 carrying an anti-friction roller 23 bearing on cam 24, while arm 21 is provided with a friction face or shoulder 25 hearing against the flanged roller 26. Cam 24 is rigidly secured to shaft 14 and is rotatable therewith, so that upon each rotation of shaft 14 the cam will operate the lever 20 for moving arm 21. The friction head or shoulder 25 on arm 21 overlaps the flange 27 on the roller 26 so that the roller 26 is properly held on its stub shaft 28 without any additional securing means. The

stub shaft 28 is rigidly secured to the slide 29 which is slidingly mounted in suitable ways 30 (Fig. 4). Slide 29 has a contact extension 31 at one end and a spring receiving extension 32 at the opposite end, extension 32 being formed with a head 33 so that spring 84 will press against head 33 and against the housing of the discharge controlling mechanism. The spring 34 normally holds slide 29 substantially in the position shown in Fig. 1, but permits the slide to be moved therefrom whenever cam 24 operates lever 20. If the set screw 36 is in substantiall the position shownin Fig. 1

the movement of slide 29 will have no effect,v

but if set screw 86 is adjusted until the end 37 is ad acent end 31 the slide 29 will force set screw 36 and the various parts connected therewith into longitudinal movement so as to intermittently open the discharge to the engine.

Housing 35 may be connected with casing 2 in any desired manner, as for instance by being threaded thereon, as shown in Fig. 3. This housing is provided with a discharge opening 38 through which all of the discharge from the discharge port 7 passes. Part of the oil discharged into passageway 38 may pass through the discharge opening 39, and part through the discharge opening 40. The opening 39 leads back to the tank from which the lubricant is drawn, while the opening 40 leads to the engine or other article being lubricated. The housing 35 is provided witha bore 41 in which a valve plunger 42 is slidingly mounted. The valve plunger 42 is provided with an enlargement 47 at one end which operates in bore 44 in the end casting 45. A spring 43 presses against head 47, and against the shoulder 49 formed at the juncture of bore 44 and bore 41 so that spring 43 will give the valve plunger 42 a continuous tendency to move toward the set screw 46. Set screw 46 may be adjusted to any desired extent for moving or adjusting the valve plunger 42 against the action of spring 43. Lock nut 48 is used for locking set screw 46 in any of its adjusted positions. The valve plunger 42 is provided with a passageway 50 which may be caused to register with the passageway 38 and discharge opening 40, or may be caused to only partially register therewith. When passageway 50 is registering with passageway 38 and discharge opening 40 all of the lubricant passing through cylinder 3 is discharged out the discharge opening 40. lVhen it is desired to reduce the amount of lubricant fed to the engine set screw46 is adjusted until the spring moves the valve plunger 42 to the desired extent, as for in stance, to the position shown in Fig. 3,

tank through the discharge port or opening 39. By adjusting set screw 46 back and forth asdesired, any desired quantity of lubricant may be fed to the engine up to the full limit of the device, the proportion of lubricant not fed to the engine returning to the tank. The adjustment of set screw 46 may be made at any time, either when the device is standing still or while it is operatmg.

Slidingly mounted upon the end 51 of housing 35 is a casting 52, which carries lugs 53 and 54, lug 54 accommodating the set screw 36, heretofore described, and lug 53 accommodating an auxiliary valve plunger 55. The auxiliary valve plunger 55 is pref erably reduced at one end for providing a pin 57 which projects through the lug 53, and which carries a suitable lock nut 58 for holding member 55 in place. As clearly shown in Fig. 5 the auxiliary valve plunger 55 is'provided with an elongated aperture 59 which is rounded at each end, and at one end is filled by a pin 60, which may be held in place in any desired manner, as for instance by a suitable retaining screw 61. The valve plunger 55 fits into a suitable bore 62 (Fig. 4) and is of such length that the plug 60 will be substantially in line with passageway 50 so that as passageway 50 uncovers the passageway 38 so as to allow the lubricant to pass to the discharge opening 40 pin 60 will cover the port or opening 39 to the same extent so that the correct proportion of lubricant will be shut off from returning to the tank. When port 50 is in complete alinement with passageway 38 the plug or pin 60 will completely inclose the opening 39 so that there will be no return of any of the lubricant to the tank. In order that the relation of the plug 60 and passageway 50 may be known an aperture 63 (Fig. 3) is provided in the end casting 52, and a depression 64 is provided in housing 35 so that when the depression 64 and aperture 63 register it will be known that the passageway 50 is registering with passageway 38. In order to prevent any rotation of the valve plunger 42 a pin or lug 65 is provided, as shown in Fig. 3, which is adapted to fit into a notch 66 (Fig. 5) in the end casting 52, which end casting cannot rotate as the same is connected with the auxiliary valve plunger 55.

In operating the device the same is connected to any desired tank or reservoir by pipe 67 so that the lubricant may flow from the tank or reservoir into the chamber 3 and be forced therefrom as above described. As the fluid passes through passageway 38 it is divided and goes through the discharge opening 40 and from thence through pipe 68 to the engine, and the other part goes through discharge opening. 39 to pipe 69 and from thence back to the tank or reservoir, this distribution taking place provided passageway 50 is only partially in registry avith passageway 38. As passageway 50 is adjusted back and forth soas to more or. 7

less register with passageway 38 the lug or member 60' is also adjusted back and forth simultaneously therewith so as to cover and uncover opening 39. By simultaneously moving the members 42 and 55 which movement may be gaged by aperture 63 any desired proportion of the fluid pumped may be caused to flow to the engine and the remaining part returned to the tank. By operating the member 42 through the adjust ment of set screw 46 a continuous flow of lubricant is provided to the engine. 1 However, if an intermittent flow or feed is desired set screw 46 is moved backward or adjusted so as to allow spring 43 to cause passageway 50 to be out of registry with passageway 38. Set screw 36 is then adjusted to be more or less in the path of movement of slide 29. The operation of cam 24 will cause the slide 20 to be moved and consequently to engage the contact point 37 of set screw 36, and thereby move the end casting 52. As end casting 52 is moved the same willmove the valve plunger 42 and cause the sameto be positioned so that the passageway 50 will temporarily register to a greater or less extent with passageway 38,

the amount of registry of these passageways corresponding to the amount of adjustment of set screw 36. It will be noted from Fig. 3 that the plunger valve 42 is securely fastened to the end casting 52 by suitable clamping nuts 7 O which rigidly hold the two parts together. As shown in Fig.1 cam 24 is provided with a small rounded end so that the passageways 50 and 38 are caused to register or partially register only for an instant and then to move out of registry.

If the end of cam 24 was broadened so as to a a valve mechanism for controlling the output of said pump, said valve mechanism having a plurality of discharge openings,

and means for adjusting said valve mechanism so as to open one discharge opening and close the other, the movement being such that one opening is being opened in the same proportion as the other is closed.
